Application led May 14, 1917. Serial No. 168,401.

To all whom it may concern:

Be it known that I, ARGYLE CAMPBELL, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Hopper-Cars, of whichthe following is a full, clear, concise, and exactdescription,'reference being had to the accompanying drawings, forming apart is a tedious and expensive operation or, the

practice has sometimes been employed of introducing a steam jet into thebody of frozen ore. The latter process requires that the -steam beinjected into the ore at different points and is an ineiicient operationinasmuch as the greater portion of the steam escapes and furthermore, itis difficult to introduce the steam in the middle or central portions ofthe load where the ore should be first thawed out.

One object of my invention is to provide an efficient arrangement ofhopper-car or ore car which permits the application of heat, as by meansof steam, to the load within the hopper to expedite thawing out thefrozen ore or other material and thus facilitate its discharge from thehoppers.

Another and more specific objecty of the invention is to provide ahopper car having steam passageways extending around and also throughthe hoppers and without sacrificing any of the vload-carryingcapacityofthe car to thereby increase the rapidity with which the loadmay be thawed out.

Further objects of the invention are to provide an efficient dooroperating mechanism more particularly adapted for cars of the type abovedescribed and also to impro-ve and strengthen the generalconstruction ofthe ore type of cars. Y

In the drawings forming a part of this specification, Figure 1 is 'apart side elevation, part longitudinal section on line 1 1, Fig. 4 of anore car showing my improvements in connection therewith. Fig. 2 is avertical, transverse sectional view of the car illustrated in Fig. 1 andtaken on lthe line 2-2 thereof, Fig. 2 being upon al larger scale thanFig. 1. Fig. 8 is a transverse sectional view, parts being broken away,the section being taken substantially on the line 3-3 of Fig. 1. Fig. 4is a horizontal sectional view, parts being broken away, and takensubstantially on the line 4 4 of Fig.A 1 and illustrating moreparticularly the arrangement of steam passageways. Fig. A5 is a verticallongitudinal sectional view taken centrally of the car to illustrate thedoor operating arrangement. Fig. 6 is an enlarged elevation and partsection of part of the door operating mechanism.` .And Fig. 7 is a topplan view of a portion of the door operating mechanism.

In said drawings, the hopper car is shown 4 as comprising vertical sidewalls 10-10; in-

clined end hopper walls 11-11, built up bod bolsters 1 2-12 (hereinaftermore particu arly described) center sills 13-13g Z- bar side sillslll-14; Z-bar end sills 15-15; a pair of hinged hopper doors 16-16; dooroperating mechanism, designated generally by the reference A; and steampassageways, hereinafter described;

. rlhe side walls 10 of the car are extended downvertically and securedto the Z-bar side sills, as indicated at 17 in Fig. 2. At the lower endsof each of the side walls, inwardly and downwardly inclined plates 18-l8are employed, the latter being secured at their upper edges to the sidewalls 10 and at their lower` edges to the inner flanges of the Z-barside sills, as indicated at 19, thereby forming outside, longitudinallyextending triangular shaped passageways B--B. The inclined end hoppersheets 11-11, just above the center sills, have s ecured theretovertical, transversely extending pressed plates 20-20, on the undersides of the end hopper walls which, in conjunction with horizontallyand transversely ex-l tending plates 21-21 also form triangular shapedpassageways lC---C that extend transversely of the car and which arealso in communication with the outside passageways B-B, as most clearlyillustrated in Fig. 4. As will be. understood, the transversepassageways C-C are closed at their outer ends by the side sheets of thecar, one

1 of the passageways C, however, having an inlet orifice 22 at one sideof the car through,

' versely and longitudinally so as to form four discharge openlngs,twoon each side of theI center still, as will be understood from an'in-`spection of Fig. 4. The longitudinal division is formed by a pair ofinclined longitudinal sheets 24--24 mounted on the tops of the centersills 1,3-13, as clearly appears' rfrom Fig..2 and said sheets 24--24 inconjunction With a horizontal 'plate 25 mounted fon the tops of thesills 13, form a center or intermediate :longitudinally extending pas'-sageway D,'the same being in communication with the'end passageways C-C,as. appears from Fig. 4. The transverse division wall of the hopper isformed by a pair of trans# versely extending plates each having a lowervertical portion 26 and an upwardly inclined portion v27, as a pearsfrom Fig'. 5. The vupper portions 2 of said transversely extendingplates in conjunction with another horizontal transverse plate 28 form acenter orintermediate transversely extending passageway E, the same'being in communication with the longitudinaly passageways B-B and D, asclearly appears from Fig. 4. In connection withv all of Athe foregoingdescribed passageways, it will be understoodl that the plates are cutaway at the. junction points in order 4to provide the necessarycommunication.

`WithV the arrangement above described it is apparent that when steam orother suitable heating medium is introduced through the orifice 22, thesteam will circulate entirely around the hopper closely adjacent thedoor openings and also through the load, .both longitudinally andtransversely', and at the same level. ln this manner, heat is applied tothe load within the hopper over an extended area, thus facilitatin thethawing outprocess. Furthermore, t e steam passageways are so disposedthat the load-carry ing capacity of the car is not lessened nor is theexpense of the carconstruction incident to the passageways appreciablyincreased.

It is also apparent that all of the plates employed in forming the steampassageways in l crease materially the strength of the car.

-Each of said hopper doors 16-1'6 extends across two of the vdischarge'openings and each door 16 is pivoted about a longitudinal axis at theside of the car, as indicated at 29, the hinge points beinlocatedbeneath the Z-bar side sills 14. long their inner edges, thedoors 16 are strengthened by suitably constructed bracing bars 30, thelatter being extended slightly beyond the doors at Iof chains isproperly guided on the sheavewheel by a central annularA rib 34.` Theends of each pair of chains 31 are connected to a balancing orequalizing linkA 35, each link 35 in turn being connected to ahook-shaped link 36, the latter in turn being pivotally connected to ashort link 37, each short link 37 being connected to another. link 38and each of the latter in turn bein connected to alever arm 39 formedintegra ly with ahub 40 mounted on a transversely lextending operatingshaft 41. As clearl appears lfrom Fig. 6, one set of links, 36, 3 and38, winds under theshaft 41 and theother set over the shaft 41 inclosely adjacent vertical planes tothereby neutralize the torsion on'the shaft when the doors are in closed position. As

Will/be understood, the hub 40 and linksv immediately associatedtherewith, together with the inner ends of thechain's 31, are located`between the center sills, and in order to provide the necessaryclearance for the ends of the lever arms 39 when vtheshaft 41 isrotated, the cover plate 2 '5 is cut away, as indicated at 42 in ig. 4,and while this opening 42 may permit-escape of a slight amount of steam,the amount which can pass therethrough' is comparatively small and maybe neglected in actual practice.

The shaft 41 is extended to both sides of the car and is provided withsuitable squared ends 43 by which it may be rotated in the usual mannerby a claw-bar or other suitable tool. The 'operating shaft 41 isprovided with suitable ratchet and pawl mechanism,

vthe latter being operable from either side of the car by means of atransversely extending auxiliary shaft 44 which extends through thecentral passageway E. A detailed description of the pawl and dogmechanism which is operable from either side of the car, will be foundin my patent for improvement in door operating mechanism, No. 1,255,385granted February 5, 1918.

Each o the holsters of the car comprises a' vertically extending plate45, saidl plate extending up tothe inclined end wall 11 of the hopperand being suitably reinforced by vertically lextending angles`46 andalso at the bottom by horizontally extending angles 47. Each 'of thebolsters 12 is also braced byl suitable plates and angles 48 extendingfrom'the vertical plate 45 to the adj acentinclined end wall 11 of thehopper. At the ends of each of the hopper doors 16, near the outer sidesthereof adjacent the hinges, downwardly extending plates 49-49 areprovided to prevent discharge of any of the load to the outer sides ofthe rails and thus insure the complete discharge of the load Within therails when the doors 16 swing open.

Although I have herein shown and described What I now consider 'thepreferred manner` of carrying out my invention, the same isfmerelyillustrative and I contemplate all changes and modiications that comeWithin the scope of the claims appended hereto.

I claim:

1. A hopper car having inclined end hopper sheets, transverselyextending vertical and horizontal sheets beneath said end hopper sheetsand forming therewith transversely extending passageways adapted toreceive a heating medium 'therewithin 2x A hopper car having inclinedend hopper sheets, transversely extending vertical and horizontal sheetsbeneath said end hopper sheets and forming therewith transverselyextending passageways adapted to receive a heating medium therewithin,and a longitudinally extending passageway in communication With saidtransversely eX- tending passageways.

In Witness that I claim the foregoing I have hereunto subscribed my namethis 28th day of April, 1917.

ARGYLE CAMPBELL.
